摘要： PROBLEM TO BE SOLVED: To prevent the appearance of overstress in a conductor due to the resonance of a rotor and an electromagnetic exciting force by making vibratory characteristics of the rotor constant, for example, by increasing a torsional natural frequency of the rotor, in a rotary machine. SOLUTION: A rotor of a rotary machine has such a structure that a part or the entire part of a head 25 of a conductor 24 may be supported in the circumferential direction and not supported in the radius direction or may be supported softer in the radius direction than in the circumferential direction. The conductor 24 is fastened to an inner circumference of a short-circuit ring 26. By eliminating a holding ring, an end of the conductor 24 can be made light-weight. As for varnish to be put in a space between the conductor and a recess of an iron core 21, hard varnish is used at a refrigerant outlet side and soft varnish is used at a refrigerant inlet side. The width of the space is made wider at the refrigerant inlet side than at the refrigerant outlet side. By this, a torsional natural frequency increases and an electromagnetic exciting force at the time of resonance becomes smaller and so, overstress does not appear in the conductor owing to the resonance of a rotor and the electromagnetic exciting force. Furthermore, vibratory characteristics of the rotor become constant and therefore overstress does not appear localy owing to the resonance of the rotor and the electromagnetic exciting force.

摘要： PROBLEM TO BE SOLVED: To improve the reliability on the superconductive magnet of a linear motor train by varying the natural frequency of at least one inner vessel out of a plurality of inner vessels from those of other inner vessels, within one outer vessel. SOLUTION: For a superconductive magnet, 8-a, 8-b, 8-c, and 8-d different in rigidity are used as the load supports 8 to support and fix four pieces of inner vessels 2-a, 2-b, 2-c, and 2-d housing superconductive coils. Then, the natural frequencies of the inner vessels 2 come to severally different values, because the spring constants of the load supports 8 are all put to different values by putting the diameters of the cylinder parts 8C-a, 8C-b, 8C-d of the load supports 8 to severally support and fix the four pieces of inner vessels 2a-2d in severally different sizes. Further, the dispersion of the natural frequency is determined to be roughly 5%. As a result, it becomes to prevent the four pieces of inner vessels from resonating at the same time, and the reliability on the supperconductive magnet for a linear motor train can be improved by reducing heat generation.

摘要： PURPOSE:To eliminate the resonance of a superconducting magnet due to a magnetic force on a traveling magnetic levitation train and prevent heat generation in the superconducting magnet by providing a case for the superconducting magnet with a damper having one end fixed and the other end pressed against the case. CONSTITUTION:A superconducting magnet 2 is mounted on the chassis 5 of a magnetic levitation train. The superconducting magnet comprises a superconducting magnet body 6, a shield plate 7 for protection from external heat, a case 8 for enclosing the superconducting magnet body, and a support 9 for carrying the superconducting magnet. The case 8 is fitted with a damper 10, which includes a base 11 fixed to the inner surface of the case 8, and a damper plate 13 that has one end in contact with the inner surface of the case and the other end bolted or welded to a slope of the upper surface of the base 11. Since the damper plate 13 is inclined with respect to the inner surface of the case, its one end is pressed against the inner surface of the case.
